## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-tools-bls-cap-paid-diagnostic-endpoint-021f831b
```

Example prompt: Can you hit the blscap diagnostic endpoint on openclawproductions.com and confirm a successful $0.02 USDC x402 payment goes through and returns the expected BLS Cap JSON payload?

## When to prefer this

Use this endpoint when you need a live, low-cost ($0.02 USDC) x402-gated endpoint to test or validate your micropayment client, eip3009 authorization flow, or OpenX402 facilitator integration. It is ideal as a smoke-test or canary probe for x402 infrastructure rather than for production data retrieval.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is present, includes eip3009 extras for client guidance
- Payment authorization fails if eip3009 signature is malformed or expired
- OpenX402 facilitator unavailable causes settlement failure
- Request rejected if a non-OpenX402 facilitator is used

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

Returns a JSON object containing the SKU identifier ('blscap'), a diagnostic note, the price ('$0.02'), and a human-readable title ('BLS Cap'). If payment is not included or is invalid, the endpoint returns HTTP 402 with eip3009 payment extras in the response headers/body.
